I call API binance /api/v3/allOrders. you can see in this URL: https://binance-docs.github.io/apidocs/spot/en/#all-orders-user_data

the response is:

[
  {
    "symbol": "LTCBTC",
    "orderId": 1,
    "orderListId": -1, //Unless OCO, the value will always be -1
    "clientOrderId": "myOrder1",
    "price": "0.1",
    "origQty": "1.0",
    "executedQty": "0.0",
    "cummulativeQuoteQty": "0.0",
    "status": "NEW",
    "timeInForce": "GTC",
    "type": "LIMIT",
    "side": "BUY",
    "stopPrice": "0.0",
    "icebergQty": "0.0",
    "time": 1499827319559,
    "updateTime": 1499827319559,
    "isWorking": true,
    "origQuoteOrderQty": "0.000000"
  }
]

but the origQuoteOrderQty get value 0 for a lot of testand a lot of orders why??

the origQuoteOrderQty is how people spend to buy some coin without include fee
